Question

I've been battling to run serve my angular project, every time I come across with some errors, I tried to find answer using google and now reached a point, where I didn't found any helpful answer. I downloaded a MEAN stack application and tried to run, but now getting the following error

ERROR in ../node_modules/@types/connect/index.d.ts:21:42 - error TS2689: Cannot extend an interface 'http.IncomingMessage'. Did you mean 'implements'?

21     export class IncomingMessage extends http.IncomingMessage {

Answer 1

@types/connect is installed with package @types/node. Version 3.4.33 (@types/[email protected]) seems to cause your problem.

I could circumvent it by installing the latest @types/node by

npm i @types/node@latest
